While we can still post heretical information...

A number of scientists are concerned about the possibility of global cooling.

Also in this article:

R. Timothy Patterson, professor of geology and director of the Ottawa-Carleton Geoscience Center of Canada's Carleton University, says that "CO2 variations show little correlation with our planet's climate on long, medium and even short time scales."

Rather, he says, "I and the first-class scientists I work with are consistently finding excellent correlations between the regular fluctuations of the sun and earthly climate. This is not surprising. The sun and the stars are the ultimate source of energy on this planet."

Then again, it is Canadian research - I'd be more concerned with cooling than warming if I were farther north, too. *wink* But starting up a carbon credit-issuing firm might be a good idea anyway, considering the socialist agenda on the menu for our upcoming election!
